Our Verdict

Dell Alienware 18 Area-51 (2025)

Dell Alienware 15 (2026)

The Dell Alienware 18 Area-51 (2025) and the Dell Alienware 15 (2026) are both gaming laptops within Dell's Alienware lineup. The Area-51 is much more performant overall, but more compromised for everyday use than the Alienware 15. It has a bigger, brighter, higher refresh rate QHD display, and significantly more powerful CPU and GPU options that deliver a much better gaming experience. That said, the Area-51's battery life is significantly worse than the Alienware 15's, in addition to it being significantly less portable on account of its massive size and weight.
